Provides a full fill firestop, installed vertically or horizontally in fire resisting walls and floors. When installed against a masonry internal skin it is suitable for use with curtain walling and profiled cladding systems or within a masonry cavity wall construction.

Description

Full fill cavity firestop which provides up to two hours' fire protection in horizontal and vertical cavities. The thickness is supplied 10 mm oversized for a compression fit and the depth of the barrier is dependent on the fire rating.

For cavities in excess of 100 mm wide, multipurpose brackets must be fitted to provide additional support. When installed against profiled cladding, the corrugations of the cladding must be filled with PFC Corofil C144 Firestop Blocks bonded into position with Fastight Coating. It is recommended that a cladding rail is positioned as close as possible to the cavity barrier to restrict movement or expansion of the cladding or the curtain walling.

Features and benefits:

  • Improved cold smoke seal when used in conjunction with Fastight Coating or foil encapsulated.
  • Improved acoustic performance when coated with Fastight Coating.
  • Third party certificated.
